Description
Technical field
The present invention relates to the energy-saving heat-preservation structure of building field, specifically a kind of building heat preservation system inside.
Background technology
Building energy conservation is imperative, but, the organic foam warming plate external thermal insulation system of present application, although have employed fire barrier, organic foam warming plate also with the addition of fire retardant, but still faces that fire retardant after several years lost efficacy, fire barrier controls the limited problem of the intensity of a fire.China is populous, city high rise building stands in great numbers, and this makes modern war and fire accident threaten the safety of China and people's lives and properties all the time.In order to reach fire safety, on March 16th, 2011, the Fire-Fighting Bureau under the Ministry of Public Security gives notice: require " civilian construction heat insulating material for external must adopt combustibility to be the material of A level ", so various thermal insulation mortar, high alumina, sulphur aluminium chemistry of cement foaming insulation board are once prevailing for a time.Unfortunately, thermal insulation mortar is too high due to coefficient of thermal conductivity, does not reach the building energy-saving standard of national requirements; And chemical blowing warming plate is counted out because later strength continues to reduce.The people want house, building energy-conservation, so the Ministry of Public Security has to and send the documents stop performing the above-mentioned file of national Fire Department.
Although organic foam warming plate still uses in building energy saving field, people do not stop the research and development of the inorganic fireproofing insulation material replacing organic foam heat insulating material a moment yet.Patent " a kind of inner wall of building insulation heat insulating construction (201320517837.4) " adopts " AX-800 compound silica heat-insulating material ", carry out inner wall of building (or exterior wall) to smear and make insulation layer, but one of composition of this material is the inorganic particulate material of " hollow ", obviously, be not hollow glass microbead be exactly hollow ceramic microballon, and this type of resource is very limited, price is also somewhat expensive.Other patents, in order to reduce costs acquisition competitive advantage, replace " hollow glass microbead " with a part of expanded perlite, vermiculite, do like this, turn increase coefficient of thermal conductivity.Also have some patents, in order to not only reduce costs but also do not increase coefficient of thermal conductivity, with all or part of replacement of polyphenyl foam particle " hollow glass microbead ", hardly realize do so worse, one is after demolishing buildings, and solid waste is recycling not easily, and be bound to contaminated environment; Two is once catch fire, although this material directly can not produce naked light under hot conditions, can produce toxic black smoke and people be fainted, goes into a coma.
Patent " a kind of inner wall of building heat-insulation system (201310017812) ", needs one or more of the too sour potassium whisker of use six, hollow glass micropearl, hollow ceramic microspheres, expanded vermiculite, concave convex rod, sepiolite, molecular sieve etc.But this heat-insulation system, because its thickness is only several millimeters, if separately by its insulation, can not reach the building energy conservation requirement of national regulation.
Also have some patents, some employing concrete, heat insulating material composite block, some employing heat insulating material sandwich heat preserving wall bodies, or the method such as special building-block is built a wall, foam concrete is built, but, there is the reduction of building intensity, troublesome drawback of constructing all to some extent in all these methods.
The patent " preparation method (201310073958) of ultralow heat conduction inorganic fireproof heat insulating plate " of Luoyang great Yu Industrial Co., Ltd. application, the inorganic fireproof heat insulating plate related to, through " National Fire building materials quality Supervision Test Center " inspection, belong to A level fire proofing material, its compressive strength, coefficient of thermal conductivity, pull strength all reach and have exceeded national sector standard " cement based foam heat-insulating board (JC/T2200-2013) ".Both can pass through building exterior wall heat preserving, also can realize building energy conservation by building heat preservation system inside, and the latter is for inorganic fireproof heat insulating plate, more can raise that it is long, keep away that it is short, play its advantage.
Summary of the invention
The object of this invention is to provide one both safe and reliable, comfortable, experience all sorts of again building heat insulation system that is durable, environmental protection.
The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of building heat preservation system inside, does following isothermal holding respectively to the inner wall surface of skin and the partition wall face that contacts with exterior wall:
In described inner wall surface and partition wall face, first smear the cement mortar that one deck is levelling, then the fissure of displacement pastes upper inorganic fireproof heat insulating plate, then after smearing the thick mortar of one deck 2 ~ 3mm, sticks alkali-proof glass grid cloth, re-uses a small amount of cement mortar floating;
The thickness of the inorganic fireproof heat insulating plate that described inner wall surface is glued with bonding mortar is 40-80mm;
The thickness of the inorganic fireproof heat insulating plate that described partition wall face is glued with bonding mortar is 20-30mm;
Other inner wall of building is not used thermal insulation material.
The pipeline laying circuit, water route, gas circuit and communication line is preset with between body of wall and warming plate.
First brushing layer of surface inorganic agent in described interior walls (namely the inner wall surface of skin and the partition wall face that contacts with exterior wall), spreads levelling cement mortar again after no-reflection moisture film on it;
Described surface conditioning agent is the acid of solid content 0-5%, and the hydrogen ion in acid is greater than 10 by acid dissociation constant
-3strong acid hydrogen ion and acid dissociation constant be less than 10
-3weak acid hydrogen ion form, and the hydrionic quantity of weak acid is the 0-100% of hydrogen ion sum.
The acid of described formation surface conditioning agent is that one or more in one or more and boric acid, oxalic acid and the citric acid in phosphoric acid, fluosilicic acid and sulfuric acid mix.
Described acid is simply phosphoric acid, preferably the mixing of phosphoric acid and citric acid, and the hydrionic quantity of weak acid is the percentage of hydrogen ion sum, and the former is 33.33%, and the latter is 36.51%.
In the present invention, the air-conditioning indoor hanging unit, smoke exhaust ventilator, geyser etc. larger to weight, can adopt longer, thicker expansion bolt to realize it and fix.
Know-why of the present invention is:
Organic foam warming plate also once for building inside holding, because the probability caught fire at indoor organic foam heat insulating material is too high, after change architectural exterior insulation into.This changes, although the probability caught fire reduces, but once catching fire is exactly that a building all catches fire.Inorganic fireproof heat insulating plate, compared with organic foam warming plate, maximum advantage be can not burn, long service life, cost of production are low, with environmental friendliness, easily construct; Maximum shortcoming is thermal conductivity ratio organic foam insulation plate hight, and has hygroscopicity.The common drawback of inorganic fireproof heat insulating plate and organic foam warming plate is that weatherability is all not as good as ordinary concrete.Therefore, to inorganic fireproof heat insulating plate, adopt the method for building inside holding, its performance advantage can be played better.
But, cause between bi-material in conjunction with hypodynamic problem because of the sequencing difference of engineering time at cement based (as the concrete) material of difference in functionality.Such as, concrete column, beam or frame construction are plastered, integrated poured concrete interface is plastered, metope leveling layer pastes foam concrete heat-preserving plate etc., all there are the problems referred to above.Even if for the float coat on unburned concrete brick, if construction wrong, also usually there is " hollowing " problem of metope.
In order to overcome the above problems, the present invention, when sticky insulation layer, first brushes layer of surface inorganic agent to strengthen bond strength in wall base surface, prevents the above-mentioned series of problems that adhesion deficiency occurs.
In the present invention, the mechanism of surface conditioning agent is as follows:
Concrete is cementitious materials with cement, and the calcium carbonate that the product after cement setting is formed nothing more than the carbon dioxide absorbed again containing cataloid, calcium hydroxide and calcium hydroxide in air.Aggregate in concrete, comprise stone, sand, flyash, slag etc., in concrete (non-aggregate exposed surface), aggregate is also all by the coating of cement setting product institute, condensation product and some non-quartz aggregate (carbonate, flyash, slag etc.) of cement can be corroded by phosphoric acid, sulfuric acid, fluosilicic acid, and the chemical reaction occurred is:
